Who I have the same questioned this topic

Have read several posts talking about mg usage happening while the user isn't even using their phone.  I check my email maybe half a dozen times a day, if that.  Don't go online and seems I'm still using over 5 but less than 10 mb per day.  I did turn the wifi on but am not really around a lot of wifi options all day.  Just want to be able to check my email a handful of times a day and maybe go on fb; and would like to stay on the $15 -150 mb plan.  i wonder if the accuweather widget/application I have on my home page is using a lot of mbs?  I have Advanced Task Killer running automatically and Lookout (virus software); other than that, I don't really go into the market place or use any other apps ...how did I do 17 mb's in two days??
